In some cases, callbacks are optional. Using "Some(function)" and "None" does not work well, because when someone writes "None" the compiler does not know what to use for "F" in "Option<F>". Therefore, adopt () to mean a "null" callback. It is possible to enforce that a callback is valid by adding a "let _: () = F::ASSERT_IS_SOME" before the invocation of F::call.

QEMU bindings and API wrappers
This library exports helper Rust types, Rust macros and C FFI bindings for internal QEMU APIs.
The C bindings can be generated with bindgen, using this build target:
$ make bindings.inc.rs
Generate Rust documentation
Common Cargo tasks can be performed from the QEMU build directory
$ make clippy
$ make rustfmt
$ make rustdoc
